Unified representation of a certain class of harmonic univalent functions defined by Dziok-Srivastava operator

Le Matematiche, 2014
In this paper, we investigate several properties of the harmonic class defined by the modified Dziok-Sirvastava operator, obtain distortion theorem, extreme points, convolution condition, convex combinations and integral operator for this class.

ON SANDWICH THEOREMS FOR CERTAIN SUBCLASSES OF ANALYTIC FUNCTIONS ASSOCIATED WITH DZIOK-SRIVASTAVA OPERATOR

Taiwanese Journal of Mathematics, 2009
In the present paper, we give some applications of first order differential subordination and superordinations to obtain sufficient conditions for normalized analytic functions defined by certain linear operators to be subordinated and superordinated to a given univalent function.

Subordinations for multivalent analytic functions associated with the Dziok–Srivastava operator

Integral Transforms and Special Functions, 2009
Let 𝒜 p (p∈ℕ:={1, 2, 3, …}) be the class of functions f given by which are analytic in the open unit disk 𝕌. Making use of the method of differential subordinations, we obtain some sufficient conditions for f(z)∈𝒜 p involving the Dziok–Srivastava operator to satisfy certain subordination properties.
